Re: [TenTec] What is the best Ten Tec Tuner

Dave:

I use a 238 tuner.  Most of the time without an amp but I do run a Centruion 
when needed.  The tuner handles all of the loads I've hung on it.  No arcs, 
no sparks.  If I identify any weakness it would be the dial cord method for 
operating the slide rule dial.  The internal SWR bridge and Power meter 
functions seem reasonably accurate.  I do not us an internal tuner with the 
new Omni VII.  And I don't mind turning a few knobs when I change bands or 
frequencies.
Antennas are a 256 ft center fed wire using balanced feed.  This antenna 
works all bands, 160M - 10M.  And a 120 ft wire using a 1:1 current balun at 
the feed point and a coax feed.  This antenna shows a 1:1 SWR at mid band on 
75M and with the tuner I work all of 80/75 meters.
